SAFETY DEVTCE FOR GAS GENERATING AND HEATING APPARATUS.
To allwkom itmag concern: Be it known that I, WILFRID- G. CHAUssE, a citizen of the United States of America,
residing at Detroit, in the county of Wayne.
and State of Michigan, have invented certain new and useful Improvements in Safety Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to a burner and a gas generating apparatus adapted to supply gas to the burner, the gas being generated from kerosene or a suitable fuel which is maintained in proximity to the burner so that the burner may be utilized for converting the fuel into a gas or vapor form.
My invention aims to provide an apparatus of the above type wherein the supply of fuel is maintained under pressure so that it will be forcibly fed to a generator subjected to the action of heat from the burner, said generator also serving as meansx for disseminating heat, so that the generator may be used as a heating medium in a stove or other structure. When using a volatile or combustible fuel, under pressure, there is a degree of danger which is materially in creased when the gas generating apparatus forms part of a car or vehicle equipment.
For instance it is the present practice to provide cars and other vehicles with a heating apparatus wherein the heat is the result of a generated gas or liquid fuel, and
' when a wreck occurs or the caror vehicle is set on fire, there is a possibility ofescaping gas or fuel being ignited and causing further damage, if not the loss of life due to explosion. It is therefore essential that safety devices be used and my invention in-- cludes a device for this purpose and in case of a fire or a collision, either of which would" injure or Wreck the heating apparatus, the gas generator is immediately rendered inoperative and the supply of fuel shut off so that it cannot escape.
My invention is further characterized by a heating apparatus that is compact, inexpensive to operate, easy to control, and highly eflici nt for the purposes for which Specification of Letters Patent.

it is intended. The mechanical construction and arrangement of parts entering into the invention will be hereinafter more fully considered and then claimed.
Reference will now be had to the drawings, wherein Devices for Gas Generating and Heating Figure l is a front elevation of the gas generating apparatus in connection with a stove;
Fig. 2 isan enlarged detail sectional view of a safety device forming part of the apparatus; g
F ig, 3 is an enlarged detail view of a portion of the gas generator, partly in section;
F ig.'4 is a vertical sectional view, partly in elevation, of another form of apparatus;
Fig. 5 is a side elevation of a stove equipped with the apparatus, and
, Fig. 6 is an elevation, partly in section, of a further form of the apparatus.
The gas generator comprises a ,central hollow body 1 having a plurality of radially disposed hollow arms 2 communicating with said body and said body and its arms may be conveniently made of tubing. In the body and its arms is placed metallic wool 3 or any non-combustible heat absorbing and bathing material through which fuel, as kerosene, may be forced, disintegrated, bafiied and heated'to that extent as to be converted into gas.
The lower end of the hollow body 1 is providedwith a reducing connection 4withwhich communicates a fuel supply pipe 5 having a shut oif valve 6 and said fuel supply pipe communicates with the bottom of a fuel ganir 7 adapted to contain kerosene or other The upper 'end'of the hollow body 1 is connected by a pipe 8 to a burner 9 in proximity to the generator, so that the flames from the burner will be directed against the generator and heat the arms and body thereof, causing the fuel passing through the generator to be converted into gas and burned at the burner.
To force the fuel into the generator, under 1 10 has a pipe 11 communicating with a twoway valve 12, which is normally open. The pipe 11 may be provided with a pressure gauge 13 and a shut off valve 14.
The two-way valve 12 is connected by a pipe 15 to a T connection 16 and said T connection communicates with the top of the fuel tank 7 through the medium of a pipe 17. Another pipe 18 establishes comr unication between the T connection 16 and a two-way valve 19, said two-way valve having an exhaust pipe 20 open to the atmosphere. The pipes 15 and 18 are placed in alinement so that the two-way valves 12 and 19 will be superposed and these valves have the plugs thereof provided with weighted stems or levers 21 and these stems or levers have ends thereof connectedby a safety device which maintains the valve 12 open and the valve 19 closed against any action by the weights 22 on thestems or levers.
The safety device comprises connectors 23 paratus. Assuming that the generatorhas an initial heat, the valves 14 and 6 are open, and the'air from the .tank 10 passes through the pipe 11, valve 12, pipe 15, connection 16 and pipe 17 into the fuel tank, on top of the fuel therein, causing the fuel to be forced upwardly in the pipe 5'and into the gas generator, where it is converted into gas to burn at the burner 9. V
Should an accident occur, for instance by fire, the fuses 24 will melt and release the ends of the valve stems orlevers 21, permitting the normally open valve 12 to close and the normally closedvalve 19 to open. The supply of air is therefore shut off from the fuel tank' and such air that remains in the fuel tank is permitted to exhaust through the valve 19 and the pipe 20. It is therefore obvious that the flow of fuel to the gas generator will be discontinued. and result in a cessation in the operation of the apparatus.
As shown in Fig. 1, the gas generator may be conveniently located in a stove structure 31 and the safety device located in a compartment 32 of the stove structure or at some. point where the fuses are protected from the heat of thestove.
Should an accident occur that would wreck the stove structure, then the sudden vibra- .work 34 supporting a pipe 35 establishing communication between valve bodies 36 and 37,- and in said valve bodies are valves 38 and 39 respectively, said valves being connected by a valve rod 40 provided with a turnbuckle 41 so that the longitudinal di mension of the valve rod may be increased or decreased to insure proper seating of the valves at the ends thereof. The valve rod 40 extends through suitable stufling boxes 42 of the valve bodies 36 and 37 and connected to said valve rod, intermediate the ends thereof, is a weighted lever 43 which has the inner end thereof pivotally connected, as at 4.4, to the pipe 35 and the outer end of said lever'has a weight 45;
The valvebody 36 is in communication with an. air supply pipe 46 and the valve body 37 withan exhaust pipe 47 and an'outlet pipe 48 adapted to communicate with a 'fuel' tank.
On the outlet pipe 48 is a, socket 49. for a 8 spring supported yieldable cup 50 which supports a safety device 51 somewhat similar to the safety device previously describedand "shown in Fig. 2, with theexce'ption thatthe safety device 51 has a fuse. 52 connecting said safety device a); the levei" 43. Then again, the weight or.,disrupting member. of the safety device isco'nnecte'd t'o the outlet pipe 48 by a flexible member 53, asa chain,
so. that saidweig'ht will at all .timesbe convenient' for' ainother' installation of. a safety device' I U As in the formpreviously described, one
of the valves "is always open, "and theother closed, so that air may passfrom the, air tank to the'fu 'el tank and forcefuel through the generator. Whenth'e safety device. 51 releases the weighted lever 43, said lever immediately. shifts the valve rod 40, closing the valve 38 and opening the valve 39 so that any air within the fuel tank may exhaust to the atmosphere.
Another form of my invention has been illustrated in Fig. 6, and this form obviates the necessity of using two valve bodies and two weighted levers. A single four-way valve 54 is employed, said valve communi-,
eating with an air tank 55, thetop Of. a fuel tank 56, the bottom of said tank, and also the gas generator so that whenthe plug 57 in the four way valve is properly positioned the air from the tank 55 may pass into the tank 56 and force the fuel out of said tank upwardly and through the four-way valve to the gas generator. The plug 57 of the fourway valve has a Weighted lever .58 asso iated Fl -QEBS QQQ with a safety device 59, similar to the safety device 51. In case of a fire or collision the lever 58 is released and the plug 57 is partially rotated, the rotation of said plug being limited'by a stop 60 of the valve, whereby the plug will shut off the supply of air to the fuel tank and also the supply of fuel to the valve, thus preventing the escape of airor fuel during a cessation in the operation of the apparatus.
My invention is not necessarily confined to use in cars or vehicles but may be used as a heating apparatus for general purposes, and while in the drawings there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such variations and modifications as the scope of the appended claim a What I claim is 1- 1. Thecombination of a gas generator, a
fuel supply.tank communicating therewith,
